ABSTRACT
Inhibin A is a significant hormone in the female reproductive system, produced primarily by the ovaries, which plays a critical role in regulating the menstrual cycle and maintaining hormonal balance. This hormone's functions include inhibiting the secretion of follicle-stimulating hormone (FSH), promoting ovarian follicular development, and influencing pregnancy outcomes. The diagnostic value of Inhibin A extends to the assessment of ovarian function, pregnancy monitoring, and identifying certain reproductive disorders, such as ovarian tumors or polycystic ovary syndrome (PCOS). This article aims to explore the role of Inhibin A in female physiology, its diagnostic applications, and the implications of its altered levels in various clinical conditions.
Introduction
Inhibin A is a glycoprotein hormone produced by the granulosa cells of ovarian follicles, as well as the placenta during pregnancy. It plays a key role in the negative feedback mechanism that regulates the menstrual cycle, specifically by inhibiting the secretion of follicle-stimulating hormone (FSH) from the anterior pituitary. Inhibin A levels vary throughout a woman's life, influenced by factors such as age, menstrual phase, and pregnancy status. Recent studies have highlighted the diagnostic potential of Inhibin A in monitoring reproductive health, particularly its use as a biomarker in ovarian disorders, pregnancy complications, and even certain cancers.
Materials and Methods
In this study, data were collected from various clinical sources, including women diagnosed with reproductive disorders, ovarian cancers, and those undergoing pregnancy monitoring. Serum samples from these patients were analyzed for Inhibin A levels. The methods included enzyme-linked immunosorbent assay (ELISA) for precise quantification of Inhibin A in blood samples. Patient histories, clinical diagnoses, and laboratory results were reviewed and categorized for further analysis.

1. Women with normal reproductive health (Control Group).
2. Women diagnosed with Polycystic Ovary Syndrome (PCOS).
3. Women with ovarian tumors.
4. Pregnant women (early and late stages).
- Statistical Analysis: Data were analyzed using SPSS software for correlation studies and comparison of Inhibin A levels across different groups. A significance level of p < 0.05 was used for determining statistical differences.
Results and Discussion
The analysis of Inhibin A levels across different patient groups showed significant variations. Women with PCOS exhibited higher levels of Inhibin A compared to the control group, suggesting a possible role of this hormone in the pathophysiology of PCOS. In contrast, women with ovarian tumors showed significantly elevated levels of Inhibin A, particularly those with granulosa cell tumors.
Pregnant women had a marked increase in Inhibin A, with levels peaking in the first trimester and gradually decreasing thereafter. The highest levels of Inhibin A were observed in early pregnancy, indicating its importance in placental function.

Discussion
Inhibin A's role as a diagnostic marker for ovarian and reproductive health disorders is evident in this study. Its elevated levels in PCOS may reflect the hormonal imbalances typical of this condition. The significantly high Inhibin A levels in ovarian tumors, particularly in granulosa cell tumors, underscore its potential as a tumor marker. Furthermore, the variation in Inhibin A levels throughout pregnancy highlights its importance in fetal development and placental function.

Our findings also suggest that Inhibin A could be a useful marker for assessing ovarian reserve and guiding fertility treatments, especially in women with fertility issues.
Conclusions
Inhibin A plays a crucial role in the regulation of the menstrual cycle and reproductive health. Its diagnostic potential extends to assessing ovarian function, detecting reproductive disorders, and monitoring pregnancy. Elevated Inhibin A levels in certain clinical conditions, such as PCOS, ovarian tumors, and pregnancy, offer valuable insights into disease mechanisms and patient management. Further research is needed to refine its use as a diagnostic and prognostic marker in clinical practice.
